A study on the microbial transformation of glycyrrhetinic acid (GA) was conducted by a fungus, Cunninghamella blakesleeana CGMCC 3.970 systematically. After incubation with the cell cultures of C. blakesleeana CGMCC 3.970 at 25 degrees C for 7 days on a rotary shaker operating at 135 r x min(-1), GA was converted into one major product and five minor products. The products were extracted and purified by solvent extraction, macroporous adsorbent resin, silica gel column chromatography, and semi-preparative RP-HPLC chromatography. Their structures were identified as 3-oxo-15α-hydroxy-18β-glycyrrhetinic acid(1), 3-oxo-15β-hydroxy-18β-glycyrrhetinic acid (2), 7β,15α-dihydroxy-18β-glycyrrhetinic acid (3), 3-oxo-7β, 15α-dihydroxy-18β-glycyrrhetinic acid (4), 7β-hydroxy-18β-glycyrrhetinic acid(5) and 15α-hydroxy-18β-glycyrrhetinic acid(6) by the analyses of MS, 1H-NMR and 13C-NMR spectroscopic data respectively. Among them, 2 was a new compound. These results suggest that C. blakesleeana CGMCC 3.970 has the capability of selective ketonization and hydroxylation for GA.

OBJECTIVETo investigate the effect of rat mesenchymal stem cells (MSCs) transfected with different oncogenes differentiate into hepatocellular carcinoma (HCC) in vitro.

METHODSMSCs, transfected with different oncogenes c-myc, K-ras, c-myc and K-ras and amplified in vitro, were infused into rats via vena portae. The recipient rats were divided into the hepatic impairment group, which were fed with tetrachloromethane and the healthy control group. At day 7, 14, 21, 28 and 42 following grafting, the complete livers were obtained and examined using fluorescence detection, conventional pathology and immunohistochemistry detection of GFP, c-kit and AFP to study the colonization and distribution of stem cells in rat liver.

RESULTSNo immunological rejection occurred after grafting of allogenic MSCs. The infused MSCs colonized in the recipient rat liver. Liver tumors were present in 6 rats grafted with MSCs that were transfected with K-ras, K-ras and c-myc, and the protein expression of AFP was detected using immunocytochemistry at day 7. Rats grafted with MSCs that were transfected with c-myc gene had no obvious tuberosity or tumor. Small oval cells were found microscopically in the periphery of vena portae, and immunohistochemistry staining of AFP was negative. Immunohistochemical staining of c-kit was positive in all livers of rats that were transfected with MSCs.

CONCLUSIONSHepatocellular carcinoma may derive from genetically mutated MSCs.

Objective To explore the effect of recovery sleep on the executive function after 36 h of total sleep deprivation by event related potential technology.Methods Thirteen healthy male college students participated in two trials. At the first trial normal sleep as control was investigated. At the second trial participants experienced 36 h of sleep deprivation and then accepted 8 h recovery sleep. In each trial six Go/Nogo tests were employed to test the executive control function and the ERP data were recorded. Results There was no statistical difference in behavior and ERP results at each time point as the subjects had normal sleep. After 36 h of sleep deprivation, the behavior results were statistically significant when compared to the baseline. The amplitude and latency of Nogo-N2, Nogo-P3 on Fz electrode, the amplitude and latency of Nogo-P3 on Cz electrode showed statistical significance when compared to the baseline. After 8 h recovery sleep, the average correct reaction time and the Go correct reaction rate had statistical significance compared to 36 h value. The amplitude of Nogo-N2 and Nogo-P3 had no statistical significance compared to the baseline.However,it was of statistical significance[(-6.80 3.95)vs(-3.37 2.63)μV,(10.63±6.62)vs(5.63±5.45)μV,(9.49±7.37)vs(6.08±6.56)μV] compared to 36 h value. The latency of the recovery value of Nogo-N2 and Nogo-P3 was statistically significant[(254.14±15.55)vs(243.08±13.97)ms(382.14±41.07)vs(349.17±30.36)ms,(369.86±26.48)vs(347.48±29.24)ms]compared to the baseline.Conclusion As the time of sleep deprivation is prolonged, the executive function is impaired and the executive function is not completely recovered after 8 h recovery sleep.

Objective To observe the effects of acupuncture at "Sanyinjiao" (SP6) and "Baihui" (GV20) on behaviors and contents of monoamine neurotransmitter dopamine (DA), noradrenalin (NE) and 5-hydroxytrypamine (5-HT) in prefrontal cortex (PFC) of attention deficit hyperactivity disorder (ADHD) rats; To discuss mechanism of action of acupuncture for prevention and treatment of ADHD. Methods 4-week-old SHR rats were randomly divided into the model group, Western medicine group and acupuncture group, and WKY rats with the same age were selected as the normal control group, with 10 rats in each group. Acupuncture was applied to "Sanyinjiao" (SP6) and "Baihui" (GV20) of rats in acupuncture group for 15 min. The rats in Western medicine group was given MPH (ritalin) for gavage, and rats were treated for 4 weeks in the dark-phase. Open field test (OFT), elevated plus maze (EPM) and novel object recognition test (NORT) were conducted to evaluate the spontaneous activity, impulsivity and learning-memorial ability of rats individually at the end of treatment. Contents of DA, NE and 5-HT in PFC were detected by HPLC. Results Compared with the normal control group, all of the behavior parameters of rats in model group were significantly higher (P＜0.05), and the contents of DA, NE and 5-HT in PFC of model group were lower than those of normal control group (P＜0.05). Compared with the model group, acupuncture group showed shorter movement distance, less rearing and fewer grooming activities in the OFT; percentages of times of entering the open arms and staying duration were reduced in the total period in the EPM; preference index in the NORT was elevated (P＜0.05); the contents of NE and 5-HT in PFC of acupuncture group increased significantly (P＜0.05). Conclusion Acupuncture at "Sanyinjiao" (SP6) and "Baihui" (GV20) canreduce the spontaneous activity and impulsivity, and improve learning and memory ability of ADHD model rats, which may be related to elevated contents of NE and 5-HT in the PFC.

Objective To evaluate the characteristics of 99Tcm-ciprofloxacin and explore its feasibility in early detection of secondary infectious foci of severe acute pancreatitis (SAP).Methods Ciprofloxacin was labeled with 99Tcm.The labeling efficiency and radiochemical purity of 99Tcm-ciprofloxacin were calculated and its biodistribution in normal pigs was measured.The recruited baby pigs were divided into three groups:normal control group (6), non-infected group (6) and infected group (16).370-400 MBq of 99Tcm-ciprofloxacin was injected into each pig intravenously.SPECT scanning was performed at 0.5, 1,2, 3, 4 and 6 h after administration.The differences of 99Tcm-ciprofloxacin uptake among groups were calculated and the tracer activity ratio of lesion-to-background was recorded at each time point.The diagnostic value of 99Tcm-ciprofloxacin SPECT imaging for the dectection of secondary infection of SAP was assessed using histopathological results as the gold standard.Variance analysis and least significant difference test were used to analyze the data.Results Both the labehing efficiency and radiochemical purity of 99Tcm-ciprofloxacin were over 90% within 6 h.Organs with rich blood supply, such as kidney, liver and spleen were the target organs for the accumulation of 99Tcm-ciprofloxacin; while no significant uptake was found in gastrointestinal tract or normal pancreas tissue of SAP.Rapid plasma clearance and renal excretion were observed.In the infected group, the lesion was visualized at 1 h after administration.The highest radioactivity ratio of lesion-to-background (3.36 ± 0.33) was at 3 h after administration, which was significantly higher than that of the other time point ( F =99.570, P ＜0.001 ).The sensitivity, specificity, positive and negative predictive values, Youden's index (YI) and Kappa value of 99Tc%ciprofloxacin imaging were 88.2% (15/17), 83.3% (5/6), 93.8% ( 15/16), 71.4% (5/7), 0.715 and 0.667 respectively.Conclusions The biodistribution of99Tcm-ciprofloxacin is suitable for imaging infectious focus of SAP.The optimal imaging time for the detection of secondary infection of SAP is 3 h after administration, with high sensitivity and specificity.

OBJECTIVETo investigate the multiple iron metabolism-related genes expression, its regulation by iron and the expression correlation among the genes in rat tissues.

METHODSTwo groups (n=30) of Sprague-Dawley female weanling rats were fed with a control diet and an iron deficient diet respectively for 4 weeks. All rats were then sacrificed, and blood and tissue samples were collected. The routine blood examination was performed with a veterinary automatic blood cell analyzer. Elemental iron levels in liver, spleen and serum were determined by atomic absorption spectrophotometry. The mRNA expression of genes was detected by real-time fluorescence quantitative PCR.

RESULTSAfter 4 weeks, the hemoglobin (Hb) level and red blood cell (RBC) count were significantly lower in the iron deficient group compared with those in the control group. The iron levels in liver, spleen and serum in the iron deficient group were significantly lower than those in the control group. In reference to small intestine, the relative expression of each iron-related gene varied in the different tissues. Under the iron deficiency, the expression of these genes changed in a tissue-specific manner. The expression of most of the genes significantly correlated in intestine, spleen and lung, but few correlated in liver, heart and kidney.

CONCLUSIONFindings from our study provides new understandings about the relative expression, regulation by iron and correlation among the mRNA expressions of transferrin receptors 1 and 2, divalent metal transporter 1, ferritin, iron regulation proteins 1 and 2, hereditary hemochromatosis protein, hepcidin, ferroportin 1 and hephaestin in intestine, liver, spleen, kidney, heart, and lung of rat.
